CVE-2021-44840Public exploitNetwork attack vector

Authenticated risk-label tampering via query endpoint

Published Jan 18, 2022 · Updated Aug 4, 2024

Authorization bypass in Delta RM 1.2 allows remote authenticated users to alter risk labels through the /core/table/query endpoint. The endpoint accepts POST parameters tableUid and datas[query] to edit, create, or delete Priority Indication, Quality Evaluation, Progress Margin, and Priority labels without enforcing the required authorization boundary. An unprivileged user can also export Criticality labels, causing unauthorized integrity changes and confidentiality loss in risk-label data.
